​Hey Hey Hey KatyCats! Pop superstar Katy Perry just released a behind-the-scenes look at the making of her latest music video for her song “Hey Hey Hey,” off of her 2017 album, Witness. The video for “Hey Hey Hey” -- which finds Perry all dolled up in a gigantic wig and dressed like an royal from a past century -- was released last month, and this making of video follows Perry’s trend of releasing behind-the-scene looks of each music video from her Witness era.
